Abstract

A new beacon management method for stations (STAs) in power saving mode (PSM) in case of congestion is suggested in this paper. When the downlink network load reaches a certain level, an access point (AP) cannot transfer its whole pending packets to the STAs during one beacon transmission interval because the length of beacon transmission interval is not so long but short and fixed. This results in unnecessary power consumption of STAs which are in idle mode compared with that of STAs in sleep mode. So, our proposed scheme restricts the number of STAs to be marked in traffic indication map (TIM) field of beacon within appropriate range according to the length of the beacon transmission interval when congestion occurs. Performance regarding power consumption is evaluated and its application to delay reduction of packets with high priority is proposed.
